Macrochan is a gigantic archive of ancient 4chan images. It doesn't have image upload support, and has changed hands many times. Currently, it uses PHP as it's backend.
Because of it's 45,175+ image collection containing 4.6GB of images that date from 4chan's earliest history, it would be a massive tragedy if the site were to ever collapse. The latest image came from around 2012, so this site is definitely abandoned.
This is a (completed) effort by the Bibliotheca Anonoma to archive Macrochan, using custom built Python scraping scripts to reduce strain on the server, and avoid the many pitfalls encountered by scraping an automatically generated database view.
The entire tag structure with all image tags have been stored in a easy to query, relationally matched SQLite database. In addition, all TagTree hierarchal parent tags have been applied to all child images, just as the current owner always wanted.
